Answer:
(-x+3)+(x+5)= -x+3+x+5. =now add the numbers -x+8+x = now combined like terms = 8 now 8 is the answer
Answer:
e
Step-by-step explanation:
you can use this phrase to help u
5 or above give it a shove
4 or below let it go
meaning that if its 5 or more then you round up but if its less then 5 then u round down
The two problems are almost identical: you have to set up a system, and then solve it.
In the first case, let and be, respectively, the number of girls and boys.
We know that (the number of girls in the Spanish Club is four more than twice the number of boys). Also, we know that (there are 61 students in total).
So, we have the system
We can use the first equation to substitute in the second
And then solve for :
For the second problem, let and be the number of pins knocked down by, respectively, Carrie and John. Just like before, we have the system
And you can solve it in the very same way we solved the previous one.
Answer:
h = 13cm and b= 54cm.
Step-by-step explanation:
We have that the area and the base is two centimeters longer than four times the height, that is
where b is the base and h the height. Now, the area is
.
Now, we are going to use the general formula to solve quadratic ecuations:
where a=4, b= 2 and c= -702.
or
As we are searching for the lenght, we choose the positive result:
.
Answer: The given series neither converges nor diverges.
Step-by-step explanation: We are given to determine whether the following series converges or diverges :
If the series converges, we are to find its sum.
The given series can be written as :
We note that the given series is a geometric one with first term 1 and common ratio given by
We know that a geometric series with common ratio r converges if |r| <1 and diverges if |r| > 1.
Since |r| = 1 for the given series, so the series will neither converge nor diverge.
Thus, the given series neither converges nor diverges.
